Improvements in Machines for 'Twisting in Warp- Threads in' Looms; and I do hereby declare the following to be a full, clear, and exact description of. the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being hadl to the accompanying drawings, and

Thisinvention relates totwisting-inachines; and its object is to provide amachine of this nature whose special adaptation is the twisting together and thus uniting of the ends of threads orother similar filaments'. I have constructed such a machine with the ideamainly of applying it to the operation` of twisting in A new warpsin the process of weaving, and thus employing it to supersede the usual hand operation, which is tedious and involves considerable expense in the matter. of time and 'labor necessarily employed.

vThe inventonconsists. in a machine for twisting together and thus uniting the ends of threads or other similar filaments constructed substantially as hereinafter described and I have iuliyillustrated my invent-ionin the accompanying drawings, wherein corresponding letters of reference indicate like,- parts, and whereinf Figure 1 7is a front view of lmy twistingmachine shown as mounted yin au operative position upon a supportprovided for it and secured to some suitable beam of a loom.

' The main frame of the machine consists of Va bed-platea, upon which are disposed two uprights ct a?, which uprights may form integral portions of the bed-plate and the one of which, a, is higher than the other.

The machine is su orted in an o erative position onthe loom by means o5 a bracket or series ofbrackets b, upon which is secured a metallic strip b',whereon the bed-plate rests and with which it Lhas a dovetailed tongueand-groove connection, adjustment being effected by means ofa thumb-screw b2, which. is mounted in the bed-plate and bears against The strip b' is adjnstably mounted on the brackeor brackets b by means of a bolt c', having a wing-nut c2 and penetrating a slot c of each bracket.

eThe bracket (or brackets) 'b is secured to a rest (Z, the same consisting of a pair of parallel plates d', adaptedto receive and be secured in any desired manner to some suitable beam at the rear of theloom, said plates being connected by a pair of integral flanged and spaced strips d2, between'which a bolt c.

projects, said bolt being also provided with a tion of the racket b. 4nly one of the strips d2 appears, wing to the position from which wing-nut c and beingsecured in the rear por# Yroo sectional non-circular forni.

Theadjustable support which I have provided makes it possible to adjust the machine either vertically, laterally, -or to and from the loom.

fis a bracket which extends horizontally and rearwardly from the upright u', said bracket being bifurcatcd, so as to form a pair of parallel. guides f', the extremities of vsaid bracket being spread apartandreceiving the upright, being bolted thereto. The free outer end of this bracket provides a bearing for the upper end of a vertical shaft f2, said shaft being stepped in the bed-plate. In the two uprighis is journaled another shaft g, and this shaft and the vshaft f2 carry bevel-gears g' g2, respectively. Rotary motion is imparted to the shafts through their respective bevel-gears from either-,of a pair of bevelgears h, the one of which is carried upon a stub-shafth and the other upon a stnb-shat`t h2. Each of these stub-shafts is journaled in 'the free end lof an arm z', which projects rear- Wardly from the upright a2, and the stubshaf't h' carries a crank i', whereas the other one carries a pulley i2, Therefore either ymachine or manual power may be utilized to trnl'y maintained in position in said plate by means of shoulders 7e', which they carry, and nuts k2. These 'hook-bars k penetrate sleeves l, journalcd inthe upright a', and for a distance corresponding to their range of movement in their reciprocations with the platel j they are preferably rectangular in cross-sec tion, though they may be of any other cross- Itshould be remarked that the inside shapes of the'sleeves Z, which they penetrate, correspond to their own shapes.

Each of the sleeves-Z is provided with a flange Z', which abuts against the rear face of the upright a', and each of said sleeves is also provided witha pinion Z2, which is somevwhat spaced from the flange by an integral annular projection which it carries.l The several sleeves are maintained in position in their bearings in the-upright a and with their flanges Z' against the face of said upright by means of a disk m, said disk beingsecitred to the upght by means of a bolt m' andproperly spaced from said upright by a collar m2, which the bolt penetrates. In order when occasion requires, as hereinafter Iexplained, that the hook-bars may be manually turned, cach flange Z', carries a spring-actuated pawl n, whose point normally engages a disposed directly bcsdethe other.

Mapas' notch 'n' in the projection of the pinion, the shape of the notch being such that the pinion cannot be rotated in the proper direction 7o without also rotating the sleeve, (and consequently the corresponding hook-ban) and yet said sleeve may be manually rotatedin the same direction f ree of the pinion.

A rotary movement is imparted to the sev-A eral pinions l2 by means of a gear-wheel o, which surrounds the pinions and, together with the disk m, provides a casing therefor, said gear-wheel 'having its teeth on its inner periphery. This. gear-wheel carries a star- 8e wheel of, havinga'lternate notches and shallow recesses o2 o. 'llhe star-`wheel is adapted to be intermittently actuated by'a pin-wheel p, the curved portion ofthe periphery of this cam being adapted to. freely work in each of 85.

-tho recesses ofthe star-wheel and its finger p being adapted to engage the notches of said star-Wheel. I y

A reciprocating motion is imparted to the frame carrying the hook-bars by means ofa 9o cam 122, having a cam-slot p in Aits npper face, saidV cam being suitably secured upon the shaf/tfZ/and its slot being adapted to receive a pin p4, that projects downwardly from the blockj I q is a revoluble shaft that is jonrnaled in the uprights a a, somewhat below but a. little to one side of the shaft g, said shaft q beving prevented from endwise movement by a crank q', secured upon its rear end, and a colloo 'lar q2, said collar and the crank. abutting against the opposite sides of the vupright a2. This shaft is adapted to be rotated from the shaft g through suitable gearing,consisting of bevel-gearing q and .bevelgearing qone of the gears in each of these two sets being secured upon a shaft r, that is journaled in a slightly-inclined bracket'l", secured to the u pright a2.

' s is a rock-shaf t which is also journaled in x the uprights a' a2, below and to-cne side oF/ `the shaft g', said rock-shaft being prevente from lengthwise movement by, a zcollar s', which it carries, and acrank s, whic'his secured to its end, said collar and the crank x 15 abutting against the twosidesof the prights a?, the same as the corresponding parts on the shaft q. yUpon the back face of the upright a2 is fnlcrmned upon a screwt a leverf t', hav ing a curved slot t, which receives the crankzzo pin of the crank q', the free ond of said lever t having pivotally secured to it one end of a pitman u, whose other end is provided with a pin u', that works in a longitudinal slot u2 in the crank s. It will be seen thatthc rotation x25 of the, shafts imparts, through mechanism above described, oscillations to the shaft s.

The hook-bars k are provided neer'their outer ends with bent spurs or hooks v. It should be remarked that there are twoy pairs 13o of these hook-bars, the one being preferably The corresponding hooks in the two pairsproject in the samedircction-thatis to say, they are esente f `arranged on the bars at corresponding points thereon but the hooks of each pair project in relatively-opposite directions.

- .Upon the rock-shaft s and near the forward ,end thereof is secured a spreader or'finger o'. One side of thisspreader or iinger, the one adjacent the upright a', is approximately straight, While the other or outer side is a curved, the npper end of" the spreaderterini nating in a sharpened point c", which as the shaft rocksalinost approaches the hook-bars Viewing this spreader or finger edgewise,

is to say, in the direction of the hook-bars. It is adjustably secured upon the rock-shaft by means of two integral sleeves r3. which Upon the outer end of the shaftq is mounted the movable vmember o f the twisting mechanism proper. AThis device consists of a curved plate w, constituting a. hook and carried by tion of the hookwith the shaft q.

an arm w', which preferably forms an integral radial portion of said hook and projects from .the shaft q. The free end of this hook is sharply tapered and it has a curvature to one `sicli-lihat is to say, toward the upright (dJ-as Well as a curvature in the direction of rota- It should be remarked that the point of the hook er:- tends approximately as far as the vertical, plane parallel to the upright ct', with which the outer or curved edge ot the spreadcrv" is coincident.

Upon the outer face ot the plate in' is disposed a shoe to2, said shoe preferabiy conv sisting of a curved strip of rubber o1-'other similar material offering a suiiicient grippingsnrface,which strip is secured in position by means of another plate wtshown in dotted lines in Fig. 6,) around Whose edges the edges of thernbher strip extend, being clamped between the two plates.

Near the forward end of the strip rc2 the edge ol' the plate w and also of the plate w3` is cut away, andin the recess formed is sc f cured the cutter, (shown in Fig. 10,) said cut- "ter consisting of a curved blade w, that extends approximately concentrically with: the' plate w and has its free end terminating in an elongated point or spur w. .It should be -rcrnarkcd that this spur does not follow the direction of th hook in so far as the lateral projection thereof hereinbefore referred to is concerned. The blade is provided with a shank 21:6,.having an elongate/d slot 107, which a screw w penetrates and whereby the blade is adjustably secured in position in the recess 6'5` after disclosed.

the plate' and basan inclined edge, the plate `wf* being cnt away to receive this projection.

The funetioniof this detlector will be hereina. c5 are a pair ofparallel rods lwhich prooutwardly from the nprightc', being disries an operating-handle is;

posed in a horizontal pianefbetween that of the shaft g and of the shaft s. These two rods carry the stationary member of the twisting mechanism proper. This member consists of .a ,carved plate b5, having anarm in, which is penetrated bythe' two rods, there being a nut 117 .on the end. of one of the rods and a spring b3 between said not and the arm.

This spring renders the plateyielding in thedirection ot the iength of the rods. "UpOn its acting face is secured 'by 'means fof-"another curved plate c5, that is riveted oscrewed to the vpiste b5, (and in the saine inariferiiiother respects as the rubber stripis sec red tb the acting face of the movable mernber obthe twisting mechanism) a rubber strip c".\"\ It should -be remarked that theplate b? is dise.

posed substantially concentrieally with reerence to the shaft (jj-#that iste say, so tha in each revointionof the shaft q the movable' member oi the twisting-mechanism will be wbrought into ehicient operative position relatively to the stationary member. It is of stituting the acting eerie-ees of lthe two meml bers ot' the device wipe the one upon the other, the ,uniformity of the contact being augscented by virtue of the yielding arrangement of the stationary member. The end of the .plate b5 toward which the movabie member of the mechanism first approaches in each revelation is shodwith e removable tip d5, that nts upon the said end of the plate and has its acting edge provided with a double and curved bevei, as at d. ,it should be re.- marltedthat, for a purpose hereinafter set forth, the face of the rubber strip c6- ot the stationary member has a transverse notch (Z7.

The' upper end of the upright is toiturcated, thereby forming a vcrticai slot'e. In this slot is adapted to reciprocate vertically a horizontal spindle e, vwhich penetrates a,

squared cross-arm e7, the portion e of ythe spindle which works in the slot being squared andthe rear end ofsaid spindle being re.

The upright a is provided with two laterallyprojecting arms7t5, in eachl of which there are mounted three parallel rods la, pro- F jecting outwardly. Over one set of these :rods the ends of the old warp is adapted to extend, while vthe ends of the new warp extend over the other one. k7 are Aother rods disposed parallel to the rods 7.96 andlmounted `in the lower ends of downwardly-projecting bars les, said' bars being suspended from a crossbar 71:9, that is secured upon and movable with lthe vertical shaft f5. The crossbar 7o is clamped to the shaft by virtue of a block 751, set into the cross-bar and secured thereto by screws Z5., and in orderto render the connection between the bars 7t5 and the cross-bar kg adjustable the former are provided with longitldinal slots l'which are' penetrated byscrews Z7 in the cross-bar,v whose ends, it maybe remarked, are bifurcated to receive said hars ks.

miis a reciprocating shaft which is mounted;

in the two .uprights a' and a? and whose forward end is provided with a block m6, in which are screwed the rear ends of threadguides im?, whose free ends are tapered and project into approximate contact with each other. It should be remarked that these thread-guides are provided with adjacent longitudinal ribsm", which aiord a reduced bearing-surface for the threads, as shown in The shaft m5 is cam 115, mounted, on the shaft f 2 and provided with a cam-slot n, 'receiving a pin nl on the rear end of said shaft.

o's is a rod that is suspended from the-endof the spindle .e6 and carries a clip o, which is upwardly and are secured the one one side adjustably secured on said 'rod and the'funcfshown in dotted lines in Fig. 1, from oppo site. sides thereof,`each extending under the outermost corresponding rod 7.56 and then over the nexttwo rods 7.a to the guides mi, under which they also pass. From here they extend and the other the other side of the spindle c by means of the grips g5. It should be remarked that the threads of each warp arc divided into two sets comprising "the alternate threads of tira warp, and that these two. sets are arranged to intersect each other and are placed in the machine in this disposition, the

intersection of the two-sets of thread (when the warps are in position in thermachine) in each warp being disposed between the upper and lower hook-bars of each pair of hook-bars which, between the. guides Im7 and the c1ampving device, project between, and thus keep separated the two sets. This is most clearly shown in Fig. 1. Hence it willbe seen. that if the two setsof threads in each Warp are so disposed with reference to the hooks on the hook-bars (which, it should -be remembered,

are in each pair of said hook -bars on rclativelyopposite sides thereof) that'said hooks act to hold or keep back that set of which the -iirst or outermost thread is the second thread of the warp, while theother set, which is ,not engaged by said hooks, is the one having the first or outermost thread of the warp, this thread in each warp will he free to separate from the others so long as atension that tends to dispose it in a straight line is eected and the other threads are held backv by the retracted hook-bars and by -virtueof their intersecting disposition relatively to each other. In other words. the hook-bars hold `together `one set' of threads, while this set of threads holds back all the threads ofthe other set except the rst or outermost one, which is the firstV or outermost thread of the entire warp. A rotary motion being imparted' to the shaft g from either the crank 2" or the pulley 2 through' the connecting 'bevel-gear. ing, the shaft will be driven, carrying with it in its rotations the cam p2, which, in an obvious manner, will impart a reciprocating movement to the frame which drives and carries the hook-bars. It being,r assumed, therefore, that the tension on the warps' is being uniformly maintained and that the rotation of the shaft g imparts, through the cam p andthe star-wheel d', ah intermittent semirevolution to each of the hook-bars 7.: as they assume their most advancedgpositions, the

outermost thread in each warp will be leftA separated from the others after thel hooks make their semirevolutions and retract, taking with them the main body of'each warp.

yIt will be apparent in view of what has been thread away from the others and toward they twistinginechanism proper. It will bc apparent that this oscillation of 'the finger o 1s effected by virtue of the mechanism shown in l v Fig. 4, which receives its actuation through the gearing g3 q, the shaft r, and the shaft q, and the crank q. NVhile the iingeror spreader is infits lowermost or substantiallyhorizontalposition, thc hook of the movable IOO said movable member and the station ary mem ber. Asthje movable member continuesto revolve the twisting of thef` is-elected.

It should be remarke I is point that whilethe cutting and twji ing; operation is progressing the 'guides miare advancedtov their extreme outward position, this being of course effected by the cam '11.5, which is mounted on the shaft f 2 and rotates therewith. Thusl the separated threads arekept under the control of the guides just as the main body of them are; but since the points of 'the guides are broughtinto approximate contact,

with each other,as shownin Fig. 14, the upwardly deflected portions in said threads .which are undergoigg the twisting process are brought into effective contiguity with each othe1".` The guides continue to hold the separated threads until the twisting operation is almost completed. As the movable member of the twisting device continues to revolve the body portion of 'the thread toward which it revolves i'sof course brought .between the rubbing-faces of.' the device, as well as are the but when this thread reaches the notch d" in the rubber strip of thestationary member of the twisting device it ceases .to move farther until said deflected ends, which are being twisted about each other, reach it,whereupon it is taken up by them and the twisting continues.- .The result of the twisting is that the deected ends arel twisted in with the body of oneof the two' ,threads being joined. lf there is any possibility of the threads thus joinedandmade as one clinging to the-rubber face of the movable member, this is obviated by the defiector w", which coacts with the tension maintained on the thread to force said thread slightlyto one side.

It has been found in practice that the iibers of the threads to be separated tend to cling to the main body of threads and that this can V be overcome if the threads are moved lon gitudinally over some stationary part-as, for instance, the vhook-bars and the rods k6 and m7. I-have therefore provided means for low-- erng the clamp which sustains the threads,

6o and also,consequently,l said threads. v This l means consists of the shaft ff, which carries the clamp and whichby virtue of the Vblock j, having the curved slot js, which receives the pin i1 on the disk je, carried by said shaft, can be lowered as the; shaft g rotates. Of course the dropping ofthe cla'mp tendsto re; duce the tension on the threads but I have? sof the thread deflected upturned ends of the two threads;A

.provided means'for compensating: for this, y

.which consists of the rods k7, carried-.on` the arms ks, that project fronrthe shaft f5, said rods being movable i'rertically, as shown in Fig. 1, between two of the rods k6.'

That portion of the extremities of thev threads which is cut and left suspended in the clamp is fed into the clip o* by the action of the outer or curvedk face of thenger or spreader ru' and there maintained until the uniting of all the threads has been effected, whereupon these ends may be discarded.-

It has been hereinbefore remarked that the hook-bars lare 'so arranged that they can be turned in one direction independently of that' portion of their actuating means which vtends to rotate them. This provision ismai-nly made so that when the threads, are arranged with reference to the hook-bars previously to starting the machine said hook-bars can be manually manipulated to facilitate the arrangef ment.

Having thus fully described my invention, what I- claim as new, and desire to secure b'y Letters Patent, is
